Abstract (en)
A variable bit rate coding system has less degradation of the quality of a decoded signal with respect to packet-by-packet signal abandonment to thereby ensure a stable quality and has high coding efficiency. The variable bit rate coding system is characterized in that a sequence of digital signals is divided into signals of a plurality of band areas, and the divided signals are encoded frame by frame. The present system as a whole eliminates the correlation or redundance of the input signal, thus ensuring highly-efficient encoding of the input signal, and maintains the quality of the decoded signal on the receiver side at a constant high level, enhancing the coding efficiency. <IMAGE>
